HEATING- PLAN'I FOB HOUSES AND BUILDINGS IN GENERAL.

To all whom it may concern:

Be it known that I, Grosnrrn Scream, subject of the King of Italy, residing at Abano, in the Province of Padova, Italy, have invented new and useful Improvements in Heating Plants for Houses and Buildings in General (forwhich I have filed an application in Italy Feb. 26, 1920), of which the following is a specification.

The present invention relates to improvements in heating plants for buildings and has for its object to provide a system of central heating consisting of a double walled stove in the interior of which the circulation of continually renewed fresh air from outside is secured.

By means of the system as specified herein below in detail, the heating of many rooms at a time with a reduced consumption of fuel can be obtained.

Another advantage of this system is that the stove can have any form whatever convenient to the room in which it is situated, account being taken that one square meter of heating surface is needed for each 100 cubic meters of air to heat.

In the accompanying drawing wherein an approved embodiment of the invention is illustrated The figure is a diagrammatic sectional view of a portion of a building illustrating the improved heating appliance applied thereto. 7

Referring to the drawing in detail the stove is formed with a closed space between the two walls a and I), made of sheet metal arranged a short distance from one another so as to leave a closed space 0 between them, the angles formed by the sheets being curved.

A tube (Z set at the bottom of the stove communicates with the space 0 and opens on the outside of the building, so as to suck pure air and continually feed it to the said space 0 and from there, when heated, to the various rooms, this tube, which can be placed above or below the floor, having a section of from 10 to 20 centimeters square accord ing to the cubic capacity of the rooms to be heated the stove being provided with a fuel feeding opening e for the fire chamber, the fire grate, indicated in dotted-lines at g and ash room 7.

A tubei entering the combustion; chamber of the stove discharges the gases of combustlon at a point outside, whilst the tubes Z and m, which communicate with the space 0 of the stove conduct the hot air into the Various rooms, another tube It opening outside the'building feeding fresh air under the fire-grate g.

The tubes Z and we take the hot air from the upper part of space a and enter into rooms, their discharge ends being turned downwa ds so as to direct the incoming warm air downwardly within-the rooms.

When the fire is lit, the lower plate of the stove will be heated at nearly 900 degrees C. soas to take a red color, and fresh air from outside entering through the tube 03 will continually be fed to the space 0, the a1r being heated by contact with the-inner wall 7) and rising, it is conducted by the tubes Z and m to the various rooms.

Having now described and specified my present invention and in what manner it must be performed, I now declare that what I claim is:

A hot air stove of double wall structure, the respective walls of the body of the stove being arranged in spaced relation to provide an air chamber extending throughout the top, bottom and sides thereof, a fire grate supported in the stove, a combustion chamber, an ash pit, a plurality of warm air conducting tubes communicating with the air space at the extreme top of the stove body and having downwardly directed discharge ends adapted for location in rooms to be heated for directing the incoming warm air downwardly therein, an air supply tube having its inlet end arranged externally of the building structure to receive fresh atmospheric air and having; its discharge end connected with the air space centrally of the bottom of the stove" body to insure equal distribution of the rising annular column of air within the air chamber, an air conducting tube communicating with the interior of the stove body below the grate and a flue communicating with the fire chamber.

In testimony whereof I have signed my name to this specification in the presence of a subscribing witness.
